ACTv17, how to use 2 email addresses for mail merge

On the contact page, I have fields for 3 emails, business/personal/spouse. When I do a mail merge to email, Act only uses the first (business) email address. I have several contacts where I would like to have the email sent to the spouse email or personal email at the same time during a mail merge. Is this possible?

I guess a different way of asking this is "what is the method that ACT uses to select the email address during an email merge"?

Thank you for submitting your post. The issue you are having may be resolved by checking out our Knowledgebase at http://kb.act.com.

Unfortunately, there is not a way to choose between Personal/Business/Spouse email addresses with the Mail Merge feature. Mail Merge only uses the default email address of the contact. When sending to one contact, you may add the other email addresses in the “To” or “CC”. However, this does not work then sending to multiple contacts.
